[0019] Alternatively, the area of ​​the first display area is configured to be different from the area of ​​the second display area, and the distance between the first sub-portion and the second bending area is different from the distance between the second sub-portion and the second bending area.

[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0050] Please refer to Figure 1 In some embodiments, the display panel includes a display area AA and a non-display area NA adjacent to the display area AA, and the display panel can be bent according to a virtual bending line 1 to achieve a folding function of the display panel, and a bending area WA is formed around the virtual bending line 1, and the portion of the display panel within the bending area WA can be curved; at the same time, two ICs 2 are respectively set for driving the display areas AA located on both sides of the virtual bending line 1; correspondingly, two fan-out areas are formed in the non-display area NA to input signals of the two ICs 2 respectively; and a fan-out trace 3 is provided in each fan-out area.

[0051] Among them, since the fan-out line 3 needs to be transmitted to different areas within the display area AA, the fan-out line 3 needs to extend divergently to connect to different areas within the display area AA; when the fan-out line 3 extends into the bending area WA, and then when the display panel is bent, the fan-out line 3 will also bend, and will be affected by the bending stress, making the fan-out line 3 prone to breakage, thereby affecting the stability and display effect of the display panel.

[0052] Please refer to Figure 2 An embodiment of the present application provides a display panel, which includes a display area 101 and a non-display area 102 adjacent to the display area 101, the display area 101 includes at least one first bending area 1011, and the non-display area 102 includes at least one second bending area 1021 adjacent to the first bending area 1011.

[0053] The display panel further includes a data line 11 , a binding portion 20 and a fan-out line 30 ; the data line 11 is disposed in the display area 101 ; the binding portion 20 is disposed in the non-display area 102 ; and the fan-out line 30 is connected between the binding portion 20 and the data line 11 .

[0054] Among them, the fan-out line 30 includes a first line segment 31 set in the display area 101 and a second line segment 32 set in the non-display area 102, the first line segment 31 is connected between the second line segment 32 and the data line 11, and the end of the second line segment 32 away from the first line segment 31 is electrically connected to the binding part 20, and the second line segment 32 is set outside the second bending area 1021.

[0055] During the implementation and application process, the embodiment of the present application sets the second line segment 32 in the fan-out line 30 outside the second bending area 1021, thereby avoiding the second line segment 32 from bending when the display panel is bent, reducing the bending stress on the fan-out line 30, reducing the probability of the fan-out line 30 breaking due to bending stress, improving the bending performance of the display panel, and thus improving the stability, service life and display effect of the display panel; and because the embodiment of the present application sets the first line segment 31 in the fan-out line 30 in the display area 101, the number of wiring in the non-display area 102 can be reduced, reducing the space of the non-display area 102, which is conducive to achieving a narrow frame of the display panel.

[0056] For details, please refer to Figure 2 The display panel includes a display area 101 and a non-display area 102 adjacent to the display area 101, wherein the non-display area 102 can be arranged around the display area 101; for example, the non-display area 102 can include a border area and a binding area of ​​the display panel.

[0057] In some embodiments, the display panel includes a data line 11 disposed in the display area 101 , a binding portion 20 disposed in the non-display area 102 , and a fan-out line 30 , wherein the fan-out line 30 is connected between the binding portion 20 and the data line 11 .

[0058] The display panel may include a driving component 200 bound to the binding portion 20 , and the fan-out line 30 may be electrically connected between the driving component 200 and the data line 11 to transmit a data signal to the data line 11 .

[0059] It can be understood that the embodiments of the present application also include other signal lines or driving circuits arranged in the display area 101 or the non-display area 102, and other fan-out signal lines, and the fan-out signal lines can be connected between the binding part 20 and the other signal lines or driving circuits to realize the transmission of other signals; and in the diagrams provided in the embodiments of the present application, only the data line 11 and the fan-out line 30 are shown for illustration.

[0060] In some embodiments, the non-display area 102 also includes a binding bending area 1023 arranged between the display area 101 and the binding portion 20, and the binding portion 20 can be bent to the back side of the display panel through the binding bending area 1023 to reduce the width of the lower border of the display panel, which is conducive to achieving a narrow-border display of the display panel.

[0061] It should be noted that the display panel provided in the embodiments of the present application includes a virtual bending line 12, and the display panel can be bent along the virtual bending line 12 to achieve the foldable function of the display panel. However, the virtual bending line 12 does not exist in the display panel product and is only a virtual line shown to illustrate the function and structure of the display panel.

[0062] When the display panel is bent along the virtual bending line 12, a first bending area 1011 is formed in the display area 101 of the display panel and a second bending area 1021 is formed in the non-display area 102; that is, the display area 101 includes the first bending area 1011, the non-display area 102 includes the second bending area 1021, and the first bending area 1011 and the second bending area 1021 are aligned and adjacent to each other; the virtual bending line 12 is located in the first bending area 1011 and the second bending area 1021, and the virtual bending line 12 is located in the middle area of ​​the first bending area 1011 and the middle area of ​​the second bending area 1021.

[0063] In some embodiments, the second bending region 1021 is located on a side of the display region 101 close to the binding portion 20 . Further, the second bending region 1021 is located on a side of the first bending region 1011 close to the binding portion 20 .

[0064] In some embodiments, the display panel includes a first state and a second state. When the display panel is configured in the first state, the display panel is flat; when the display panel is configured in the second state, the display panel is curved in the first bending area 1011 and the second bending area 1021.

[0065] In an embodiment of the present application, the display panel includes a fan-out line 30 arranged in the non-display area 102 and connected between the binding portion 20 and the data line 11. The non-display area 102 also includes a fan-out area 1022 located between the binding bending area 1023 and the display area 101. The fan-out line 30 can be connected to the data line 11 at different positions in the display area 101 in a divergent radial pattern in the fan-out area 1022, so that the distribution density of the fan-out line 30 in the fan-out area 1022 is relatively large; since the part of the display panel located in the second bending area 1021 will be bent, therefore, if the fan-out line 30 is located in the second bending area 1021, it will be subjected to greater bending stress, and thus it is easy to cause adverse phenomena such as breakage, affecting signal transmission and display effects.

[0066] However, since sub-pixels are distributed throughout the display area 101 of the display panel, and the data line 11 needs to be connected to each column of sub-pixels to provide data signals, the data line 11 will be distributed in various areas of the display area 101; and the fan-out line 30 needs to connect all the data lines 11 in the display area 101, and the area of ​​the divergent radiation area of ​​the fan-out line 30 in the fan-out area 1022 is larger, which inevitably causes the fan-out line 30 to be distributed in the second bending area 1021.

[0067] In the embodiment of the present application, a portion of the fan-out line 30 is extended into the display area 101 and is bent in the display area 101 to be connected to the data line 11, thereby reducing the area of ​​the divergent radiation region of the fan-out line 30 in the non-display area 102, avoiding the fan-out line 30 from being set in the second bending area 1021, and reducing the bending stress on the fan-out line 30.

[0068] Specifically, the fan-out line 30 includes a first line segment 31 arranged in the display area 101 and a second line segment 32 arranged in the non-display area 102, the second line segment 32 is connected between the binding portion 20 and the first line segment 31, the first line segment 31 is connected between the second line segment 32 and the data line 11, and the second line segment 32 is arranged outside the second bending area 1021. In the embodiment of the present application, the second line segment 32 in the fan-out line 30 is arranged outside the second bending area 1021, thereby preventing the second line segment 32 from bending when the display panel is bent, reducing the bending stress on the fan-out line 30, reducing the probability of the fan-out line 30 breaking due to bending stress, improving the bending performance of the display panel, and thus improving the stability, service life and display effect of the display panel; and because the embodiment of the present application arranges the first line segment 31 in the fan-out line 30 in the display area 101, the number of wirings in the non-display area 102 can be reduced, reducing the space in the non-display area 102, which is conducive to achieving a narrow frame of the display panel.

[0069] In some embodiments, the first bending region 1011 extends along the first direction M, the second bending region 1021 extends along the first direction M, and the first bending region 1011 and the second bending region 1021 are adjacent to each other along the first direction M; in addition, the first direction M is the extension direction of the data line 11; at the same time, the first direction M is the extension direction of the virtual bending line 12.

[0070] Correspondingly, the display panel includes multiple fan-out lines 30, the extension direction of the second line segments 32 in some of the fan-out lines 30 is parallel to the first direction M, and the extension direction of the second line segments 32 in some of the fan-out lines 30 intersects with the first direction M; that is, in the embodiment of the present application, the second line segments 32 can still extend in a divergent radial shape, but the radiation area will be reduced, and the second line segments 32 will not extend into the second bending area 1021.

[0071] In some embodiments, the extension direction of the side where the first line segment 31 is connected to the second line segment 32 is parallel to the first direction M, and the extension direction of the side where the first line segment 31 is connected to the data line 11 intersects with the first direction M; for example, the extension direction of the first line segment 31 on the side connected to the data line 11 can be perpendicular to the first direction M; that is, the second line segment 32 can first extend along the first direction M, and then extend along a direction perpendicular to the first direction M to the corresponding data line 11, and connect to the corresponding data line 11; that is, the original fan-out line 30 needs to radiate to the position of the corresponding data line 11 within the fan-out area 1022, but in the embodiment of the present application, the second line segment 32 is extended to the corresponding data line 11 in the display area 101 along a direction perpendicular to the first direction M, thereby effectively reducing the radiation area of ​​the fan-out line 30 in the fan-out area 1022.

[0072] In some embodiments, the first line segment 31 whose extension direction is parallel to the first direction M is located outside the first bending zone 1011, and the first line segment 31 whose partial extension direction intersects the first direction M is located inside the first bending zone 1011; since there are sub-pixels and data lines 11 in the first bending zone 1011, the first line segment 31 connected to the data line 11 located in the first bending zone 1011 will extend into the first bending zone 1011, and the first line segments 31 connecting the data lines 11 located outside the first bending zone 1011 are all located outside the first bending zone 1011, which can minimize the bending stress on the fan-out line 30.

[0073] In some embodiments, please refer to Figure 2 The display panel also includes a functional signal line 63 at least arranged in the non-display area 102 , and part of the functional signal line 63 is located in the second bending area 1021 , and the toughness of the second line segment 32 is less than the toughness of the functional signal line 63 .

[0074] That is to say, in the embodiment of the present application, the second line segment 32 with less toughness is arranged outside the second bending area 1021, while the functional signal line 63 with greater toughness is retained in the second bending area 1021. On the one hand, the probability of the signal line breaking due to bending stress is reduced, and on the other hand, it avoids the complexity of the display panel process and increased cost due to the large number of adjustments to the wiring layout.

[0075] In some embodiments, the functional signal lines 63 may be used to provide various required signals to the pixel driving circuit in the display area 101 .

[0076] In some embodiments, the material of the second line segment 32 includes molybdenum, and the material of the functional signal line 63 includes a stacked metal structure of Ti / Al / Ti.

[0077] In some embodiments, please combine Figure 2 、 Figure 3 、 Figure 4 as well as Figure 5 The display panel includes a substrate 41, a semiconductor layer 44 arranged on the substrate 41, a gate insulating layer 42 covering the semiconductor layer 44, a first conductive layer 50 arranged on the gate insulating layer 42, an interlayer insulating layer 43 covering the first conductive layer 50, and a second conductive layer 60 arranged on the interlayer insulating layer 43.

[0078] In which, the display panel also includes a thin film transistor arranged in the display area 101, and the thin film transistor may include an active portion 441, a gate 51, a source 61 and a drain 62; in which, the semiconductor layer 44 includes an active portion 441, the first conductive layer 50 includes a gate 51, and the second conductive layer 60 includes a source 61 and a drain 62.

[0079] It should be noted that thin film transistors can not only be distributed in the display area 101, for example, located in the pixel driving circuit; at the same time, thin film transistors can also be set in the non-display area 102, for example, located in the gate driving circuit, and the figures in the embodiments of the present application only take the thin film transistors located in the display area 101 as an example for explanation.

[0080] In some embodiments, when the display panel is an OLED display panel, the display panel also includes at least one flat layer disposed on the second conductive layer 60, an anode layer and a pixel definition layer disposed on the flat layer, an organic light-emitting layer disposed on the anode layer, a cathode layer disposed on the organic light-emitting layer, and an encapsulation layer disposed on the cathode layer.

[0081] In some embodiments, the first conductive layer 50 includes a second line segment 32 disposed in the non-display area 102; the second conductive layer 60 includes a functional signal line 63; and the second line segment 32 is located in the fan-out area 1022, and the functional signal line 63 can be located in the second bending area 1021 and the fan-out area 1022.

[0082] In some embodiments, the binding portion 20 includes a first sub-portion 21 and a second sub-portion 22 arranged on opposite sides of the second bending area 1021, and the first sub-portion 21 and the second sub-portion 22 can be arranged on opposite sides of the second bending area 1021 along the second direction N, and the first direction N and the second direction M intersect; correspondingly, the first sub-portion 21 is bound and connected to the driving component 200, and the second sub-portion 22 is also bound and connected to the driving component 200; and the first sub-portion 21 and the second sub-portion 22 are both connected to the corresponding data line 11 through the fan-out line 30.

[0083] In some embodiments, the first direction M is perpendicular to the second direction N.

[0084] In an embodiment of the present application, the binding portion 20 provided with the driving component 200 is split into a first sub-portion 21 and a second sub-portion 22, and the first sub-portion 21 and the second sub-portion 22 are both located outside the second bending area 1021, thereby reducing the influence of bending stress on the first sub-portion 21 and the second sub-portion 22, and further improving the binding stability of the driving component 200 in the display panel.

[0085] The display area 101 also includes a first display area 1012 and a second display area 1013 located on opposite sides of the first bending area 1011. The first sub-section 21 is connected to the data line 11 in the first display area 1012 through the fan-out line 30, and the second sub-section 22 is connected to the data line 11 in the second display area 1013 through the fan-out line 30. The first sub-section 21 and the second sub-section 22 are arranged at intervals; that is, in the embodiment of the present application, the part of the binding portion 20 located in the second bending area 1021 can be removed, thereby reducing the film layers and structures involved in the bending in the display panel, and effectively improving the bending performance of the display panel; at the same time, the binding portion 20 can be avoided from participating in the bending along the virtual bending line 12, which can further reduce the influence of the bending stress on the first sub-section 21 and the second sub-section 22, and further improve the binding stability of the driving component 200 in the display panel.

[0086] In some embodiments, the spacing between the first sub-section 21 and the second sub-section 22 is greater than or equal to the width of the second bending zone 1021 along the second direction N; preferably, the spacing between the first sub-section 21 and the second sub-section 22 is greater than the width of the second bending zone 1021 along the second direction N; the stress pulling of the binding portion 20 by the film layer or structure of the bent portion in the display panel can be reduced.

[0087] Furthermore, the area of ​​the first display area 1012 and the area of ​​the second display area 1013 may be the same or different, that is, the bending of the display panel may be symmetrical or asymmetrical.

[0088] In some embodiments, as Figure 6 As shown, the width of the first sub-portion 21 along the second direction N is equal to the width of the second sub-portion 22 along the second direction N. When the area of ​​the first display area 1012 and the area of ​​the second display area 1013 are configured to be the same, the spacing between the first sub-portion 21 and the second bending area 1021 is equal to the spacing between the second sub-portion 22 and the second bending area 1021. In addition, the first sub-portion 21 and the fan-out line 30 connected to the first sub-portion 21 are connected to the second sub-portion 22 and the fan-out line 30 connected to the second sub-portion 22 relative to the second bending area. The area 1021 (virtual bending line 12) is symmetrically arranged; the position and arrangement of the first sub-section 21 and the fan-out line 30 connected to the first sub-section 21, and the position and arrangement of the second sub-section 22 and the fan-out line 30 connected to the second sub-section 22 are symmetrically arranged relative to the second bending area 1021 (virtual bending line 12); thereby, the arrangement, force and impedance of the fan-out line 30 in the display panel can be symmetrical, which is beneficial to the display uniformity of the first display area 1012 and the second display area 1013.

[0089] In other embodiments of the present application, when the area of ​​the first display area 1012 is configured to be the same as the area of ​​the second display area 1013, the distance between the first sub-section 21 and the second bending area 1021 may not be equal to the distance between the second sub-section 22 and the second bending area 1021, and can be adaptively adjusted according to the width or position of the first sub-section 21 and the second sub-section 22, as well as actual needs, which is not limited here.

[0090] In some embodiments, as Figure 7 As shown, the width of the first sub-section 21 along the second direction N is equal to the width of the second sub-section 22 along the second direction N. When the area of ​​the first display area 1012 is different from the area of ​​the second display area 1013, the spacing between the first sub-section 21 and the second bending area 1021 and the spacing between the second sub-section 22 and the second bending area 1021 are different. At this time, the areas of the first display area 1012 and the second display area 1013 can be differentiated according to product requirements, so that the display panel can meet the needs of folding products with more differentiated displays.

[0091] For example, the area of ​​the first display area 1012 may be smaller than the area of ​​the second display area 1013 .

[0092] In some embodiments, as Figure 8 As shown, the width of the first sub-section 21 along the second direction N is not equal to the width of the second sub-section 22 along the second direction N. When the area of ​​the first display area 1012 is different from the area of ​​the second display area 1013, the spacing between the first sub-section 21 and the second bending area 1021 and the spacing between the second sub-section 22 and the second bending area 1021 can be equal; at this time, the areas of the first display area 1012 and the second display area 1013 can be differentiated according to product requirements, so that the display panel can meet the needs of folding products with more differentiated displays; and the distances between the first sub-section 21 and the second sub-section 22 and the second bending area 1021 are equal, which can improve the force uniformity of the display panel when bending.

[0093] For example, the area of ​​the first display area 1012 may be smaller than that of the second display area 1013 , and the width of the first sub-portion 21 along the second direction N may be smaller than the width of the second sub-portion 22 along the second direction N.

[0094] In other embodiments of the present application, the shapes of the first display area 1012 and the second display area 1013 may be the same or different, and may be selected according to actual needs, which is not limited here.

[0095] In some embodiments, the display area 101 includes a plurality of first bending areas 1011, and the non-display area 102 includes a plurality of second bending areas 1021, and the plurality of first bending areas 1011 correspond to the plurality of second bending areas 1021 one by one and are arranged adjacent to each other; thereby, the display panel provided in the embodiment of the present application can be a multi-folding display panel. Correspondingly, the binding portion 20 can also include a plurality of sub-portions, and each two sub-portions can be distributed on opposite sides of a second bending area 1021, and each two adjacent second bending areas 1021 can share a sub-portion located between the two; and the settings of each second bending area 1021 and the binding portions 20 on both sides can refer to Figure 2 The embodiment shown is configured and will not be described in detail here.

[0096] In summary, the embodiment of the present application sets the second line segment 32 in the fan-out line 30 outside the second bending area 1021, thereby avoiding the second line segment 32 from bending when the display panel is bent, reducing the bending stress on the fan-out line 30, reducing the probability of the fan-out line 30 breaking due to bending stress, improving the bending performance of the display panel, and thus improving the stability, service life and display effect of the display panel; and because the embodiment of the present application sets the first line segment 31 in the fan-out line 30 in the display area 101, the number of wiring in the non-display area 102 can be reduced, reducing the space of the non-display area 102, which is conducive to achieving a narrow frame of the display panel.

[0098] It can be understood that, since the display device includes the same display panel as that in the above embodiment, the display device has the same beneficial effects as the display panel in the above embodiment, which will not be described in detail here.
